Police now believe that this explosion and two others are related. The other explosions, one more today and another from March 2nd, are all considered to be “similar” in nature. Two of these explosions have been fatal.

The second package explosion today left a 75-year-old woman in critical but stable condition.

A task force has been formed to investigate the occurrences. Police are warning residents to remain vigilant and that if they encounter any packages that are unexpected to call 911. (source)
